Answer:
37 polio vaccinations and 23 measles vaccination.
Step-by-step explanation:
Let the number of polio vaccination given=x
Let the number of measles vaccination given=y
Dr. Potter gave a total of 60 vaccinations
x+y=60
Since each polio vaccination consists of 4 doses, and each measles vaccination consists of 2 doses. A total of 184 doses was given out.
4x+2y=184
To find the values of x and y, we solve the two equations simultaneously.
x+y=60 (1)
4x+2y=184 (2)
From (1), x=60-y
Substitute x=60-y into equation 2.
4x+2y=184
4(60-y)+2y=184
240-4y+2y=184
240-184=4y-2y
56=2y
Divode both sides by 2
y=23
Recall earlier that x=60-y
x=60-23=37
Dr Potter gave 37 polio vaccinations and 23 measles vaccination.
Answer:
option a
Step-by-step explanation:
Given in the question an expression
5logx - 6log(x-6)
To solve this question we will apply two of the logarithm property
1) power rule
alogx = log
log - log
2) substraction rule
The log of a quotient is the difference of the logs
loga (x/y) = loga x - loga y
log
5.1 and the “1” is repeating
Answer:
27y - 6
Step-by-step explanation:
3(9y - 2) Multiply 3 times each term in the parentheses
3 * 9y = 27y
3 * -2 = -6
Answer: 5
Step-by-step explanation:
-7x-3x+2=-8x-8
-10x+2=-8x-8
-10x+8x=-8-2
-2x=-10
x=-10/-2
x=5
